Fluid ejecting apparatus, and fluid ejecting method

Abstract

A fluid ejecting apparatus includes a drum that rotates while holding a medium on its outer periphery, a head that ejects a fluid on to the medium held on the periphery of the drum, a fixing section that fixes the fluid ejected on to the medium by the head, a measuring section that measures a diameter of the drum, and a controller that varies an ejection timing of the fluid ejected from the head in accordance with variation in the diameter of the drum measured by the measuring section.

What is claimed is: 
     
       1. A fluid ejecting method, comprising:
 rotating a medium by allowing the medium to be held on a periphery of a drum; 
 ejecting a fluid on to the medium held on the periphery of the drum; 
 fixing the fluid ejected on to the medium by the fixing section; 
 measuring a variation of the diameter of the drum caused by heating the drum; and 
 varying an ejection timing of the fluid in accordance with the variation of the diameter of the drum, 
 wherein the variation of the diameter is measured by a laser focus type outer diameter measuring device. 
 
     
     
       2. The fluid ejecting method according to  claim 1 , wherein the fixing section is a light radiating device. 
     
     
       3. The fluid ejecting method according to  claim 1 , wherein the fixing section is a heater. 
     
     
       4. A fluid ejecting apparatus, comprising:
 a drum that rotates while holding a medium on its outer periphery; 
 a head that ejects a fluid on to the medium held on the periphery of the drum; 
 a fixing section that fixes the fluid ejected on to the medium by the head; 
 a laser focus type outer diameter measuring device that measures a diameter of the drum; and 
 a controller that varies an ejection timing of the fluid ejected from the head based upon the variation of the diameter of the drum measured by the laser focus type outer diameter measuring device. 
 
     
     
       5. The fluid ejecting apparatus according to  claim 4 , wherein the fixing section is a light radiating device. 
     
     
       6. The fluid ejecting apparatus according to  claim 4 , wherein the fixing section is a heater.
